a0f3e26245 fix(distributed): make admin backend installs resilient and observable (#9958)
* feat(distributed): add configurable NATS backend install/upgrade timeouts

Adds BackendInstallTimeout and BackendUpgradeTimeout to DistributedConfig
with 15m defaults, following the existing MCPToolTimeout / WorkerWaitTimeout
pattern. These will replace the hardcoded literals in RemoteUnloaderAdapter
so admin-driven backend installs across the cluster survive long OCI image
pulls that previously timed out at 3m.

* style(distributed): gofmt alignment after timeout fields

Re-aligns the Validate() negative-duration map and the Default* const
block so the new BackendInstall/UpgradeTimeout entries do not leave
the surrounding columns mis-padded.

* feat(cli): surface LOCALAI_NATS_BACKEND_INSTALL_TIMEOUT and _UPGRADE_TIMEOUT

Parses the two new env vars on the run CLI and threads them through the
existing AppOption builder so DistributedConfig picks them up. Invalid
duration strings now fail loudly at startup rather than silently falling
back to the default.

* feat(distributed): inject NATS install/upgrade timeouts into RemoteUnloaderAdapter

Removes the hardcoded 3m / 15m literals from RemoteUnloaderAdapter and
threads in DistributedConfig.BackendInstallTimeoutOrDefault() and
BackendUpgradeTimeoutOrDefault() at construction. Install now defaults
to 15m (was 3m); cold OCI image pulls on Jetson Wi-Fi routinely blew
past the old ceiling. Scripted messaging client captures the timeout
so tests can assert the configured value actually reaches the NATS
request.

* feat(distributed): introduce galleryop.ErrWorkerStillInstalling sentinel

When the NATS request-reply for backend.install (or .upgrade) times out
the worker is almost always still pulling the OCI image. Wrap the timeout
in a typed sentinel so the manager above can distinguish "worker hung"
from "worker still working" and leave the pending_backend_ops row in
place for the reconciler to confirm via backend.list.

* feat(distributed): treat NATS install timeout as in-progress, not failure

When a worker times out replying to backend.install but the install is
still running on the worker, enqueueAndDrainBackendOp now reports a
running_on_worker status and pushes NextRetryAt out by the install
timeout so the reconciler does not immediately re-fire another install
while the worker is still pulling the image. The pending_backend_ops
row stays in place for the next reconciler pass to confirm via
backend.list.

InstallBackend wraps the result in galleryop.ErrWorkerStillInstalling
so callers can branch (galleryop renders yellow in-progress instead of
red error). UpgradeBackend uses the same wrap.

Adds RemoteUnloaderAdapter.InstallTimeout() so the manager can push
NextRetryAt by the configured timeout without reaching into a private
field, and NodeRegistry.RecordPendingBackendOpInFlight as the soft
cousin of RecordPendingBackendOpFailure.

Also includes incidental gofmt-driven struct-field alignment in
registry.go on lines unrelated to the change (touched files are
re-formatted to canonical form per project policy).

* fix(distributed): don't increment Attempts on in-flight install timeout

An in-flight timeout (worker still pulling the OCI image) is not a
failed attempt, it's a delayed one. Incrementing Attempts let
genuinely-progressing slow installs (e.g. 30 GB CUDA images on Wi-Fi)
trip the reconciler's maxPendingBackendOpAttempts cap and dead-letter
the queue row while the worker was still legitimately working.

RecordPendingBackendOpInFlight now only updates LastError and NextRetryAt.
Also documents "running_on_worker" in the NodeOpStatus.Status enum
comment so Task 6 implementers see the full surface.

* feat(galleryop): surface ErrWorkerStillInstalling as non-error OpStatus

When the distributed backend manager returns an error that wraps
ErrWorkerStillInstalling, backendHandler now completes the op with a
"still installing in background" message rather than marking it as a
red failure. Admin UI sees a yellow in-progress state; reconciler
confirms completion on its next pass.

* test(distributed): end-to-end install-timeout-then-reconcile

Wires Task 1-6 end-to-end so any seam mismatch surfaces in CI rather
than during a real cluster install. NATS times out, the queue row
stays alive with running_on_worker status, the worker eventually
reports the backend installed via backend.list, the manager surfaces
it via ListBackends.

* docs(distributed): document LOCALAI_NATS_BACKEND_INSTALL_TIMEOUT / _UPGRADE_TIMEOUT

Add the two new operator-tunable env vars to the Frontend Configuration
table in the distributed-mode docs. Explains the 15m default, when to
raise it (slow links pulling multi-GB OCI images), and the new
"still installing in background" admin-UI state when the round-trip
times out but the worker is still working.

* feat(distributed): clear pending install rows when backend.list confirms

DistributedBackendManager.ListBackends now proactively clears
pending_backend_ops install rows whose (nodeID, backend) is reported
installed by backend.list. Operator UI updates immediately instead of
waiting up to installTimeout (default 15m) for the next reconciler
tick after NextRetryAt.

Only install rows are cleared; upgrade and delete intents are not
satisfied by presence in backend.list and continue to drain through
their normal reconciler paths.

* feat(messaging): add BackendInstallProgressEvent wire type and subject

New NATS subject nodes.<nodeID>.backend.install.<opID>.progress lets the
worker publish transient progress events (file, current/total bytes,
percentage, phase) while a long-running install pulls its OCI image.
BackendInstallRequest gains an optional OpID field so the worker knows
which subject to publish on.

Transient pub/sub (not JetStream): the install reply remains ground
truth for success/failure; dropped progress events are tolerable.

* style(messaging): drop em-dash from BackendInstallProgress test comment

Per project convention (no em-dashes anywhere). Comment substance is
unchanged.

* feat(distributed): worker publishes debounced install progress over NATS

When BackendInstallRequest.OpID is set, the worker's backend.install
handler wires a debounced publisher (250ms window) into the gallery
download callback. Each tick becomes a BackendInstallProgressEvent on
nodes.<nodeID>.backend.install.<opID>.progress; the publisher always
emits a final event on Flush so the UI sees the terminal percentage.

Old masters that do not set OpID continue to run silent installs: no
behavior change for them. Lock ordering: the publisher releases its
mutex before calling messaging.Publish so a slow network never stalls
the install loop.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* feat(distributed): RemoteUnloaderAdapter subscribes to install progress

InstallBackend gains opID + onProgress parameters. When both are set,
the adapter subscribes to nodes.<nodeID>.backend.install.<opID>.progress
BEFORE publishing the install request, decodes each message into the
caller's onProgress callback in a goroutine (so a slow callback never
stalls the NATS reader thread), and unsubscribes after RequestJSON
returns.

When onProgress is nil OR opID is empty (the reconciler retry path),
subscription is skipped entirely - silent installs cost nothing extra.

Subscribe failure is logged at Warn and the install proceeds without
progress streaming; the NATS round-trip still owns terminal status.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* feat(distributed): forward backend install progress into galleryop OpStatus

DistributedBackendManager.InstallBackend now passes the gallery op ID
and a progress bridge into the adapter call. Each
BackendInstallProgressEvent from the worker becomes a
galleryop.ProgressCallback tick - which the existing backendHandler
already turns into OpStatus.UpdateStatus, so the admin UI/SSE polling
sees per-byte progress for distributed installs without any UI-side
change.

UpgradeBackend is intentionally left silent for now: its wire request
(BackendUpgradeRequest) does not carry OpID, and rolling-update
fallback is the rarer path. Will be picked up in a follow-up if the
worker upgrade path also gets a progress channel.

* test(distributed): InstallBackend tolerates silent (pre-Phase-2) workers

A worker on pre-Phase-2 code never publishes progress events. The new
master subscribes optimistically; this spec pins that a silent worker
still produces a green install with no progressCb ticks. The install
reply is the source of truth for terminal state; the progress stream
is a best-effort UX enrichment.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* docs(distributed): document install progress streaming

Note the new nodes.<nodeID>.backend.install.<opID>.progress subject and
the silent-worker compatibility behavior so operators know to expect
real-time progress and what happens on a mixed-version cluster.

* docs(distributed): note progress-event ordering trade-off in InstallBackend

Document near the goroutine dispatch why ordering at the consumer is
best-effort, why it rarely matters in practice (worker debounce >>
goroutine jitter), and what a future hardening pass would look like
(Seq field + stale-by-seq drop). Stops the next reader from accidentally
"fixing" the goroutine pool away.

* feat(galleryop): add NodeProgress + OpStatus.Nodes for per-node breakdown

Adds the data model the UI needs to render an expandable per-node
breakdown of a fanned-out backend install. NodeProgress carries node
identity (ID + name), per-node status (queued / running_on_worker /
success / error / downloading), the current file + bytes + percentage
from the Phase 2 progress stream, and any per-node error.

OpStatus.Nodes is the slice the /api/operations handler will surface
in a follow-up.

* feat(galleryop): UpdateNodeProgress merges per-node ticks by NodeID

GalleryService.UpdateNodeProgress(opID, nodeID, np) merges a NodeProgress
into OpStatus.Nodes (keyed by NodeID, no duplicates) and mirrors the
latest tick into the aggregate Progress / FileName /
DownloadedFileSize / TotalFileSize fields so the legacy single-bar
OperationsBar view keeps working unchanged alongside the new per-node
breakdown.

Concurrent-safe via the existing g.Mutex.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* feat(distributed): write per-node OpStatus entries during install fan-out

DistributedBackendManager now accepts a nodeProgressSink and feeds it
two streams:

1. enqueueAndDrainBackendOp emits a per-node terminal entry on each
   status it appends to BackendOpResult (queued, success, error,
   running_on_worker). The opID is threaded through the function so
   the sink gets the right gallery op identity.

2. The install apply closure fans each BackendInstallProgressEvent
   into the sink as a downloading entry, alongside the legacy
   progressCb path so the aggregate single-bar view stays correct.

Production wiring passes the GalleryService (which implements
UpdateNodeProgress via Task 2) as the sink. Single-node tests pass
nil. DeleteBackend and UpgradeBackend pass an empty opID so the
sink path no-ops for ops that aren't gallery-tracked the same way
as Install.

* feat(operations): expose per-node breakdown on /api/operations

When an operation's OpStatus has Nodes entries (populated by the
Phase 4 progress sink wiring), surface them as a "nodes" array on the
/api/operations response, sorted by node_name for stable rendering.

Backward compatible: legacy clients ignore the field; ops without any
node entries (single-node mode, model installs) omit the array entirely
thanks to the empty-slice guard.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* feat(ui): per-node breakdown in OperationsBar

When an install op fans out to more than one worker, the operations
bar now shows a "N nodes" chevron that expands into a per-node list.
Each row carries the node's status (color-coded pill), the current
file being downloaded, byte counts, percentage, and a thin per-node
progress bar. Yellow "Worker busy" pill marks running_on_worker
status with a tooltip explaining the NATS round-trip timed out but
the worker is still installing in the background.

Backward compatible: ops without a nodes field (legacy or single-node
mode) render as before. State for expand/collapse is local to the
component, keyed by jobID/id - reload starts collapsed.

* docs(distributed): document per-node breakdown in the operations bar

Adds a short subsection covering the expandable "N nodes" chevron in
the OperationsBar admin UI, the meaning of each status pill, and
how it relates to the /api/operations nodes array.

* fix(galleryop): UpdateStatus preserves Nodes when caller sends none

Real-world bug surfaced by the Phase 4 multi-worker smoke test: the
nodes[] array in /api/operations flickered between a single node at a
time on a 2-worker install. Root cause: the Phase 2 progress bridge
also calls the legacy progressCb -> UpdateStatus(&OpStatus{...}) on
every tick. UpdateStatus then overwrote the entire status pointer,
wiping the Nodes slice that UpdateNodeProgress had just merged in.

Fix: in UpdateStatus, if the incoming op has an empty Nodes slice,
carry forward the previous status's Nodes before storing. Callers
that explicitly populate Nodes still win (their slice replaces the
prior one, no merge across the two code paths).

Two regression specs added pinning both directions of the contract.

* docs(distributed): strip implementation details from user-facing docs

Trim the new install/upgrade timeout rows and the install-progress
sections to focus on what the operator sees and tunes. Drops:

- the NATS subject names and pub/sub mechanics
- "round-trip" / reconciler / backend.list jargon
- /api/operations polling cadence
- "pre-2026-05-22" version references

Reframes the breakdown text around the admin UI (Operations Bar,
chevron, status pills, "Worker busy" tooltip). Implementation context
lives in the agent notes and code comments.

* refactor(config): move DistributedConfig.Validate flag names to constants

The negative-duration check map was a wall of literal kebab-case
strings that had to stay in sync with the kong-derived CLI flag names
manually. Move them to a Flag* const block alongside the existing
Default* block so a rename of either the Go field or the CLI naming
convention forces a compile error rather than silent drift.

Sole consumer today is Validate; the constants are exported so future
operator-facing surfaces (e.g. error messages on other validation
paths) can reference them by name instead of repeating the literals.

Tests pin both the literal values (so a future "let's just rename
this" doesn't accidentally regress the CLI flag) and the negative-
duration error message for the new BackendInstall / BackendUpgrade
fields.

* refactor(distributed): extract NodeStatus and Phase enums to constants

Sweep for the same literal-string-as-identifier pattern called out on
the Validate flag names: the per-node install status enum
("queued" | "downloading" | "running_on_worker" | "success" | "error")
appeared as raw literals across managers_distributed.go (10+ sites,
including 3 separate `n.Status == "running_on_worker"` checks),
operation.go, and the test suite. Same shape for the Phase enum
("resolving" | "downloading" | "extracting" | "starting") in the
worker-side progress publisher.

Promote both to exported const blocks:

- galleryop.NodeStatus{Queued,Downloading,RunningOnWorker,Success,Error}
  shared between galleryop.NodeProgress.Status (the wire field) and
  nodes.NodeOpStatus.Status (the in-process per-node summary)
- messaging.Phase{Resolving,Downloading,Extracting,Starting}
  shared between the worker publisher and any future consumer that
  needs to switch on phase

Tests pin both the literal values (so a future "let's just rename" doesn't
silently change the JSON wire) and use the constants in setup (so the
producer side stays drift-protected). Wire-format assertions on the
/api/operations JSON output keep their literals deliberately, so the
constant value can never silently diverge from what the UI receives.

Out of scope for this PR (separate cleanup): the finetune and
quantization job-status enums have the same anti-pattern with 14+
literal sites each, but predate this PR's work.

The handler previously called unloader.InstallBackend synchronously and
blocked the browser for up to 3 minutes waiting on the NATS reply. It now
enqueues a TargetNodeID-scoped ManagementOp on BackendGalleryChannel and
returns HTTP 202 + jobID immediately, matching /api/backends/install/:id.

The opcache key is built via NodeScopedKey(nodeID, backend) so concurrent
installs of the same backend across different nodes do not stomp each
other. galleryService/opcache/appConfig are threaded through
RegisterNodeAdminRoutes for this.

* feat(api): expose nodeID for node-scoped backend ops in /api/operations

Node-scoped backend installs land in opcache under "node:<nodeID>:<backend>"
keys. Without splitting that prefix back out, the operations panel renders
the full key as the display name and has no structured way to label which
worker an install is targeting. Detect the prefix, surface nodeID as its own
response field, and reduce the display name back to the bare backend slug.
Bare (non-scoped) ops are left untouched so legacy installs do not gain a
misleading empty nodeID.

0245b33eab feat(realtime): Add Liquid Audio s2s model and assistant mode on talk page (#9801)
* feat(liquid-audio): add LFM2.5-Audio any-to-any backend + realtime_audio usecase

Wires LiquidAI's LFM2.5-Audio-1.5B as a self-contained Realtime API model:
single engine handles VAD, transcription, LLM, and TTS in one bidirectional
stream — drop-in alternative to a VAD+STT+LLM+TTS pipeline.

Backend
- backend/python/liquid-audio/ — new Python gRPC backend wrapping the
  `liquid-audio` package. Modes: chat / asr / tts / s2s, voice presets,
  Load/Predict/PredictStream/AudioTranscription/TTS/VAD/AudioToAudioStream/
  Free and StartFineTune/FineTuneProgress/StopFineTune. Runtime monkey-patch
  on `liquid_audio.utils.snapshot_download` so absolute local paths from
  LocalAI's gallery resolve without a HF round-trip. soundfile in place of
  torchaudio.load/save (torchcodec drags NVIDIA NPP we don't bundle).
- backend/backend.proto + pkg/grpc/{backend,client,server,base,embed,
  interface}.go — new AudioToAudioStream RPC mirroring AudioTransformStream
  (config/frame/control oneof in; typed event+pcm+meta out).
- core/services/nodes/{health_mock,inflight}_test.go — add stubs for the
  new RPC to the test fakes.

Config + capabilities
- core/config/backend_capabilities.go — UsecaseRealtimeAudio, MethodAudio
  ToAudioStream, UsecaseInfoMap entry, liquid-audio BackendCapability row.
- core/config/model_config.go — FLAG_REALTIME_AUDIO bitmask, ModalityGroups
  membership in both speech-input and audio-output groups so a lone flag
  still reads as multimodal, GetAllModelConfigUsecases entry, GuessUsecases
  branch.

Realtime endpoint
- core/http/endpoints/openai/realtime.go — extract prepareRealtimeConfig()
  so the gate is unit-testable; accept realtime_audio models and self-fill
  empty pipeline slots with the model's own name (user-pinned slots win).
- core/http/endpoints/openai/realtime_gate_test.go — six specs covering nil
  cfg, empty pipeline, legacy pipeline, self-contained realtime_audio,
  user-pinned VAD slot, and partial legacy pipeline.

UI + endpoints
- core/http/routes/ui.go — /api/pipeline-models accepts either a legacy
  VAD+STT+LLM+TTS pipeline or a realtime_audio model; surfaces a
  self_contained flag so the Talk page can collapse the four cards.
- core/http/routes/ui_api.go — realtime_audio in usecaseFilters.
- core/http/routes/ui_pipeline_models_test.go — covers both code paths.
- core/http/react-ui/src/pages/Talk.jsx — self-contained badge instead of
  the four-slot grid; rename Edit Pipeline → Edit Model Config; less
  pipeline-specific wording.
- core/http/react-ui/src/pages/Models.jsx + locales/en/models.json — new
  realtime_audio filter button + i18n.
- core/http/react-ui/src/utils/capabilities.js — CAP_REALTIME_AUDIO.
- core/http/react-ui/src/pages/FineTune.jsx — voice + validation-dataset
  fields, surfaced when backend === liquid-audio, plumbed via
  extra_options on submit/export/import.

Gallery + importer
- gallery/liquid-audio.yaml — config template with known_usecases:
  [realtime_audio, chat, tts, transcript, vad].
- gallery/index.yaml — four model entries (realtime/chat/asr/tts) keyed by
  mode option. Fixed pre-existing `transcribe` typo on the asr entry
  (loader silently dropped the unknown string → entry never surfaced as a
  transcript model).
- gallery/lfm.yaml — function block for the LFM2 Pythonic tool-call format
  `<|tool_call_start|>[name(k="v")]<|tool_call_end|>` matching
  common_chat_params_init_lfm2 in vendored llama.cpp.
- core/gallery/importers/{liquid-audio,liquid-audio_test}.go — detector
  matches LFM2-Audio HF repos (excludes -gguf mirrors); mode/voice
  preferences plumbed through to options.
- core/gallery/importers/importers.go — register LiquidAudioImporter
  before LlamaCPPImporter.
- pkg/functions/parse_lfm2_test.go — seven specs for the response/argument
  regex pair on the LFM2 pythonic format.

Build matrix
- .github/backend-matrix.yml — seven liquid-audio targets (cuda12, cuda13,
  l4t-cuda-13, hipblas, intel, cpu amd64, cpu arm64). Jetpack r36 cuda-12
  is skipped (Ubuntu 22.04 / Python 3.10 incompatible with liquid-audio's
  3.12 floor).
- backend/index.yaml — anchor + 13 image entries.
- Makefile — .NOTPARALLEL, prepare-test-extra, test-extra,
  docker-build-liquid-audio.

Docs
- .agents/plans/liquid-audio-integration.md — phased plan; PR-D (real
  any-to-any wiring via AudioToAudioStream), PR-E (mid-audio tool-call
  detector), PR-G (GGUF entries once upstream llama.cpp PR #18641 lands)
  remain.
- .agents/api-endpoints-and-auth.md — expand the capability-surface
  checklist with every place a new FLAG_* needs to be registered.

* feat(realtime): function calling + history cap for any-to-any models

Three pieces, all on the realtime_audio path that just landed:

1. liquid-audio backend (backend/python/liquid-audio/backend.py):
   - _build_chat_state grows a `tools_prelude` arg.
   - new _render_tools_prelude parses request.Tools (the OpenAI Chat
     Completions function array realtime.go already serialises) and
     emits an LFM2 `<|tool_list_start|>…<|tool_list_end|>` system turn
     ahead of the user history. Mirrors gallery/lfm.yaml's `function:`
     template so the model sees the same prompt shape whether served
     via llama-cpp or here. Without this the backend silently dropped
     tools — function calling was wired end-to-end on the Go side but
     the model never saw a tool list.

2. Realtime history cap (core/http/endpoints/openai/realtime.go):
   - Session grows MaxHistoryItems int; default picked by new
     defaultMaxHistoryItems(cfg) — 6 for realtime_audio models (LFM2.5
     1.5B degrades quickly past a handful of turns), 0/unlimited for
     legacy pipelines composing larger LLMs.
   - triggerResponse runs conv.Items through trimRealtimeItems before
     building conversationHistory. Helper walks the cut left if it
     would orphan a function_call_output, so tool result + call pairs
     stay intact.
   - realtime_gate_test.go: specs for defaultMaxHistoryItems and
     trimRealtimeItems (zero cap, under cap, over cap, tool-call pair
     preservation).

3. Talk page (core/http/react-ui/src/pages/Talk.jsx):
   - Reuses the chat page's MCP plumbing — useMCPClient hook,
     ClientMCPDropdown component, same auto-connect/disconnect effect
     pattern. No bespoke tool registry, no new REST endpoints; tools
     come from whichever MCP servers the user toggles on, exactly as
     on the chat page.
   - sendSessionUpdate now passes session.tools=getToolsForLLM(); the
     update re-fires when the active server set changes mid-session.
   - New response.function_call_arguments.done handler executes via
     the hook's executeTool (which round-trips through the MCP client
     SDK), then replies with conversation.item.create
     {type:function_call_output} + response.create so the model
     completes its turn with the tool output. Mirrors chat's
     client-side agentic loop, translated to the realtime wire shape.

UI changes require a LocalAI image rebuild (Dockerfile:308-313 bakes
react-ui/dist into the runtime image). Backend.py changes can be
swapped live in /backends/<id>/backend.py + /backend/shutdown.

* feat(realtime): LocalAI Assistant ("Manage Mode") for the Talk page

Mirrors the chat-page metadata.localai_assistant flow so users can ask the
realtime model what's loaded / installed / configured. Tools are run
server-side via the same in-process MCP holder that powers the chat
modality — no transport switch, no proxy, no new wire protocol.

Wire:
- core/http/endpoints/openai/realtime.go:
  - RealtimeSessionOptions{LocalAIAssistant,IsAdmin}; isCurrentUserAdmin
    helper mirrors chat.go's requireAssistantAccess (no-op when auth
    disabled, else requires auth.RoleAdmin).
  - Session grows AssistantExecutor mcpTools.ToolExecutor.
  - runRealtimeSession, when opts.LocalAIAssistant is set: gate on admin,
    fail closed if DisableLocalAIAssistant or the holder has no tools,
    DiscoverTools and inject into session.Tools, prepend
    holder.SystemPrompt() to instructions.
  - Tool-call dispatch loop: when AssistantExecutor.IsTool(name), run
    ExecuteTool inproc, append a FunctionCallOutput to conv.Items, skip
    the function_call_arguments client emit (the client can't execute
    these — it doesn't know about them). After the loop, if any
    assistant tool ran, trigger another response so the model speaks the
    result. Mirrors chat's agentic loop, driven server-side rather than
    via client round-trip.

- core/http/endpoints/openai/realtime_webrtc.go: RealtimeCallRequest
  gains `localai_assistant` (JSON omitempty). Handshake calls
  isCurrentUserAdmin and builds RealtimeSessionOptions.

- core/http/react-ui/src/pages/Talk.jsx: admin-only "Manage Mode"
  checkbox under the Tools dropdown; passes localai_assistant: true to
  realtimeApi.call's body, captured in the connect callback's deps.

Mirroring chat's pattern means the in-process MCP tools surface "just
works" for the Talk page without exposing a Streamable-HTTP MCP endpoint
(which was the alternative). Clients with their own MCP servers can
still use the existing ClientMCPDropdown path in parallel; the realtime
handler distinguishes them by AssistantExecutor.IsTool() at dispatch
time.

* feat(realtime): render Manage Mode tool calls in the Talk transcript

Previously the realtime endpoint only emitted response.output_item.added
for the FunctionCall item, and Talk.jsx's switch ignored the event — so
server-side tool runs were invisible in the UI. The model would speak
the result but the user had no way to see what tool was actually
called.

realtime.go: after executing an assistant tool inproc, emit a second
output_item.added/.done pair for the FunctionCallOutput item. Mirrors
the way the chat page displays tool_call + tool_result blocks.

Talk.jsx: handle both response.output_item.added and .done. Render
FunctionCall (with arguments) and FunctionCallOutput (pretty-printed
JSON when possible) as two transcript entries — `tool_call` with the
wrench icon, `tool_result` with the clipboard icon, both in mono-space
secondary-colour. Resets streamingRef after the result so the next
assistant text delta starts a fresh transcript entry instead of
appending to the previous turn.

* refactor(realtime): bound the Manage Mode tool-loop + preserve assistant tools

Fallout from a review pass on the Manage Mode patches:

- Bound the server-side agentic loop. triggerResponse used to recurse on
  executedAssistantTool with no cap — a model that kept calling tools
  would blow the goroutine stack. New maxAssistantToolTurns = 10 (mirrors
  useChat.js's maxToolTurns). Public triggerResponse is now a thin shim
  over triggerResponseAtTurn(toolTurn int); recursion increments the
  counter and stops at the cap with an xlog.Warn.

- Preserve Manage Mode tools across client session.update. The handler
  used to blindly overwrite session.Tools, so toggling a client MCP
  server mid-session silently wiped the in-process admin tools. Session
  now caches the original AssistantTools slice at session creation and
  the session.update handler merges them back in (client names win on
  collision — the client is explicit).

- strconv.ParseBool for the localai_assistant query param instead of
  hand-rolled "1" || "true". Mirrors LocalAIAssistantFromMetadata.

- Talk.jsx: render both tool_call and tool_result on
  response.output_item.done instead of splitting them across .added and
  .done. The server's event pairing (added → done) stays correct; the
  UI just doesn't need to inspect both phases of the same item. One
  switch case instead of two, no behavioural change.

Out of scope (noted for follow-ups): extract a shared assistant-tools
helper between chat.go and realtime.go (duplication is small enough
that two parallel implementations stay readable for now), and an i18n
key for the Manage Mode helper text (Talk.jsx doesn't use i18n
anywhere else yet).

* ci(test-extra): wire liquid-audio backend smoke test

The backend ships test.py + a `make test` target and is listed in
backend-matrix.yml, so scripts/changed-backends.js already writes a
`liquid-audio=true|false` output when files under backend/python/liquid-audio/
change. The workflow just wasn't reading it.

- Expose the `liquid-audio` output on the detect-changes job
- Add a tests-liquid-audio job that runs `make` + `make test` in
  backend/python/liquid-audio, gated on the per-backend detect flag

The smoke covers Health() and LoadModel(mode:finetune); fine-tune mode
short-circuits before any HuggingFace download (backend.py:192), so the
job needs neither weights nor a GPU. The full-inference path remains
gated on LIQUID_AUDIO_MODEL_ID, which CI doesn't set.

The four new Go test files (core/gallery/importers/liquid-audio_test.go,
core/http/endpoints/openai/realtime_gate_test.go,
core/http/routes/ui_pipeline_models_test.go, pkg/functions/parse_lfm2_test.go)
are already picked up by the existing test.yml workflow via `make test` →
`ginkgo -r ./pkg/... ./core/...`; their packages all carry RunSpecs entries.

b1a99436c7 feat(branding): admin-configurable instance name, tagline, and assets (#9635)
Adds a whitelabeling feature so an operator can replace the LocalAI
instance name, tagline, square logo, horizontal logo, and favicon from
the admin Settings page. Defaults fall back to the bundled assets so
existing installs are unaffected.

The public GET /api/branding endpoint is reachable pre-auth so the
login screen can render the configured branding before sign-in.
Mutating routes (POST/DELETE /api/branding/asset/:kind) remain
admin-only. Text fields (instance_name, instance_tagline) ride the
existing /api/settings flow; binary assets get a dedicated multipart
upload route that persists files under DynamicConfigsDir/branding/.

To prevent the Settings page's stale local state from clobbering an
upload on save, UpdateSettingsEndpoint preserves whatever the on-disk
asset filename fields are regardless of the body — /api/branding/asset/*
are the sole writers for those fields.

The MCP catalog gains get_branding and set_branding tools (text fields
only; file upload stays UI-only) plus a configure_branding skill prompt.

While wiring this up, the same restart-loss class of bug surfaced for
several existing fields whose RuntimeSettings entries were never read
by the startup loader. Fix loadRuntimeSettingsFromFile() to load:

  - branding (instance_name, instance_tagline, *_file basenames)
  - auto_upgrade_backends, prefer_development_backends
  - localai_assistant_enabled
  - open_responses_store_ttl
  - the 7 existing AgentPool fields (enabled, default/embedding model,
    chunking sizes, enable_logs, collection_db_path)

Also exposes 3 new AgentPool runtime settings (vector_engine,
database_url, agent_hub_url) via /api/settings + the Settings UI, with
the same load-on-startup wiring. The file watcher's manual-edit path
is intentionally not changed — the in-process API endpoints already
update appConfig directly, so the watcher is redundant for supported
flows and a separate refactor for everything else.

15 TDD specs cover the loader behaviour (1 branding + 11 adjacent + 3
new agent-pool); 2 specs cover the persistence helpers and the
clobber-prevention contract.

2da1a4d230 feat(distributed): per-node backend installation from the gallery
In distributed mode the Backends gallery used to fan every install out to
every worker — fine for auto-resolving (meta) backends like llama-cpp where
each node picks its own variant, but wrong for hardware-specific builds
like cpu-llama-cpp that would silently land on every GPU node.

Adds a node-targeted install path through the existing
POST /api/nodes/:id/backends/install plumbing, with two entry points:

- Backends gallery row gets a split-button in distributed mode. Auto-
  resolving keeps "Install on all nodes" as the primary; chevron menu
  opens the picker. Hardware-specific routes the primary directly to the
  picker — no fan-out path on the row.
- Nodes-page drawer gets a "+ Add backend" button that navigates to
  /app/backends?target=<node-id>; the gallery scopes itself to that node
  (banner, single per-row install button, Reinstall/Remove for already-
  installed). One gallery, two scopes — no second UI to maintain.

The picker (new NodeInstallPicker) shows a 3-state suitability column
(Compatible / Override / Installed), an auto-expanding variant override
disclosure that fires when selected nodes have no working GPU, parallel
per-node installs with inline status and Retry-failed-nodes, and a
mismatch confirm that names the consequence on the button itself.

A 409 fan-out guard on /api/backends/apply protects CLI/Terraform/script
users from the same footgun: hardware-specific installs in distributed
mode now return code "concrete_backend_requires_target" with a human-
readable error and a meta_alternative pointer.

The gallery list payload now surfaces capabilities, metaBackendFor and
per-row nodes (NodeBackendRef) so the picker and the new Nodes column
have everything they need without re-walking the gallery client-side.

GODEBUG=netdns=go is set on the compose services because the cgo DNS
resolver follows the container's nsswitch.conf to host systemd-resolved
(127.0.0.53), unreachable from inside the container; the pure-Go
resolver reads /etc/resolv.conf directly and uses Docker's embedded DNS.

4906cbad04 feat: add biometrics UI (#9524)
* feat(react-ui): add Face & Voice Recognition pages

Expose the face and voice biometrics endpoints
(/v1/face/*, /v1/voice/*) through the React UI. Each page has four
tabs driving the six endpoints per modality: Analyze (demographics
with bounding boxes / waveform segments), Compare (verify with a
match gauge and live threshold slider), Enrollment (register /
identify / forget with a top-K matches view), Embedding (raw
vector inspector with sparkline + copy).

MediaInput supports file upload plus live capture: webcam
snap-to-canvas for face, MediaRecorder -> AudioContext ->
16-bit PCM mono WAV transcode for voice (libsndfile on the
backend only handles WAV/FLAC/OGG natively).

Sidebar gets a new Biometrics section feature-gated on
face_recognition / voice_recognition; routes are wrapped in
<RequireFeature>. No new dependencies -- Font Awesome icons
picked from the Free set.

* fix(localai): accept data URI prefixes with codec/charset params

Browser MediaRecorder produces data URIs like
  data:audio/webm;codecs=opus;base64,...
so the pre-';base64,' section can carry multiple parameter
segments. The `^data:([^;]+);base64,` regex in pkg/utils/base64.go
and core/http/endpoints/localai/audio.go only matched exactly one
segment, so recordings straight from the React UI's live-capture
tab failed the strip and then tripped the base64 decoder on the
leading 'data:' literal, surfacing as
  "invalid audio base64: illegal base64 data at input byte 4"

Widened both regexes to `^data:[^,]+?;base64,` so any number of
';param=value' segments between the mime type and ';base64,' are
tolerated. Added a regression test covering the MediaRecorder
shape.

* fix(insightface): scope pack ONNX loading to known manifests

LocalAI's gallery extracts buffalo_* zips flat into the models
directory, which inevitably mixes with ONNX files from other
backends (opencv face engine, MiniFASNet antispoof, WeSpeaker
voice embedding) and older buffalo pack installs. Feeding those
foreign files into insightface's model_zoo.get_model() blows up
inside the router -- it assumes a 4-D NCHW input and indexes
`input_shape[2]` on tensors that aren't shaped like a face model,
raising IndexError mid-load and leaving the backend unusable.

The router's dispatch isn't amenable to per-file try/except alone
(first-file-wins picks det_10g.onnx from buffalo_l even when the
user asked for buffalo_sc -- alphabetical order happens to favour
the wrong pack). Instead, ship an explicit manifest of the
upstream v0.7 pack contents and scope the glob to that when the
requested pack is known. The manifest is small and stable; future
packs can be added alongside or fall through to the tolerance
loop, which also swallows any remaining IndexError / ValueError
from foreign files with a clear `[insightface] skipped` stderr
line for diagnostics.

* fix(speaker-recognition): extract FBank features for rank-3 ONNX encoders

Pre-exported speaker-encoder ONNX graphs come in two shapes:

  rank-2  [batch, samples]           -- some 3D-Speaker exports,
                                        take raw waveform directly.
  rank-3  [batch, frames, n_mels]    -- WeSpeaker and most Kaldi-
                                        lineage encoders, expect
                                        pre-computed Kaldi FBank.

OnnxDirectEngine unconditionally fed `audio.reshape(1, -1)` --
correct for rank-2, IndexError-on-input_shape[3] on rank-3, which
surfaced to the UI as
  "Invalid rank for input: feats Got: 2 Expected: 3"

Detect the input rank at session init and run Kaldi FBank
(80-dim, 25ms/10ms frames, dither=0.0, per-utterance CMN) before
the forward pass when rank>=3. All knobs are configurable via
backend options for encoders that deviate from defaults.

torchaudio.compliance.kaldi is already in the backend's
requirements (SpeechBrain pulls torchaudio in), so no new
dependency.

* fix(biometrics): isolate face and voice vector stores

Face (ArcFace, 512-D) and voice (ECAPA-TDNN 192-D / WeSpeaker
256-D) biometric embeddings were colliding inside a single
in-memory local-store instance. Enrolling one after the other
failed with
  "Try to add key with length N when existing length is M"
because local-store correctly refuses to mix dimensions in one
keyspace.

The registries were constructed with `storeName=""`, which in
StoreBackend() is just a WithModel() call. But ModelLoader's
cache is keyed on `modelID`, not `model` -- so both registries
collapsed to the same `modelID=""` slot and reused the same
backend process despite looking isolated on paper.

Three complementary fixes:

  1. application.go -- give each registry a distinct default
     namespace ("localai-face-biometrics" /
     "localai-voice-biometrics"). The comment claimed
     isolation, now it's actually enforced.

  2. stores.go -- pass the storeName as both WithModelID and
     WithModel so the ModelLoader cache key separates
     namespaces and the loader spawns distinct processes.

  3. local-store/store.go -- drop the Load() `opts.Model != ""`
     guard. It was there to prevent generic model-loading loops
     from picking up local-store by accident, but that auto-load
     path is being retired; the guard now just blocks legitimate
     namespace isolation. opts.Model is treated as a tag; the
     per-tuple process isolation upstream handles discrimination.

* fix(gallery): stale-file cleanup and upgrade-tmp directory safety

Two related robustness fixes for backend install/upgrade:

pkg/downloader/uri.go
  OCI downloads passed through
      if filepath.Ext(filePath) != "" ...
          filePath = filepath.Dir(filePath)
  which was intended to redirect file-shaped download targets
  into their parent directory for OCI extraction. The heuristic
  misfires on directory-shaped paths with a dot-suffix --
  gallery.UpgradeBackend uses
      tmpPath = "<backendsPath>/<name>.upgrade-tmp"
  and Go's filepath.Ext treats ".upgrade-tmp" as an extension.
  The rewrite landed the extraction at "<backendsPath>/", which
  then **overwrote the real install** (backends/<name>/) with a
  flat-layout file and left a stray run.sh at the top level. The
  tmp dir itself stayed empty, so the validation step that
  checked "<tmpPath>/run.sh" predictably failed with
      "upgrade validation failed: run.sh not found in new backend"
  Every manual upgrade silently corrupted the backends tree this
  way. Guard the rewrite behind "target isn't already an existing
  directory" -- InstallBackend / UpgradeBackend both pre-create
  the target as a directory, so they get the correct behaviour;
  existing file-path callers with a genuine dot-extension still
  get the parent redirect.

core/gallery/backends.go
  InstallBackend's MkdirAll returned ENOTDIR when something at
  the target path was already a file (legacy dev builds dropped
  golang backend binaries directly at `<backendsPath>/<name>`
  instead of nesting them under their own subdir). That
  permanently blocked reinstall and upgrade for anyone carrying
  that state, since every retry hit the same error. Detect a
  pre-existing non-directory, warn, and remove it before the
  MkdirAll so the fresh install can write the correct nested
  layout with metadata.json + run.sh.

* fix(galleryop): refresh upgrade cache after backend ops

UpgradeChecker caches the last upgrade-check result and only
refreshes on the 6-hour tick or after an auto-upgrade cycle.
Manual upgrades (POST /api/backends/upgrade/:name) go through
the async galleryop worker, which completes the upgrade
correctly but never tells UpgradeChecker to re-check -- so
/api/backends/upgrades continued to list a just-upgraded backend
as upgradeable, indistinguishable from a failed upgrade, for up
to six hours.

Add an optional `OnBackendOpCompleted func()` hook on
GalleryService that fires after every successful install /
upgrade / delete on the backend channel (async, so a slow
callback doesn't stall the queue). startup.go wires it to
UpgradeChecker.TriggerCheck after both services exist. Result:
the upgrade banner clears within milliseconds of the worker
finishing.

* build: prepend GOPATH/bin to PATH for protogen-go

install-go-tools runs `go install` for protoc-gen-go and
protoc-gen-go-grpc, which writes them into `go env GOPATH`/bin.
That directory isn't on every dev's PATH, and protoc resolves
its code-gen plugins via PATH, so the immediately-following
protoc invocation fails with
  "protoc-gen-go: program not found"
which in turn blocks `make build` and any
`make backends/%` target that depends on build.

Prepend `go env GOPATH`/bin to PATH for the protoc invocation
so the freshly-installed plugins are found without requiring a
shell-profile change.

* refactor(ui-api): non-blocking backend upgrade handler with opcache

POST /api/backends/upgrade/:name used to send the ManagementOp
directly onto the unbuffered BackendGalleryChannel, which blocked
the HTTP request whenever the galleryop worker was busy with a
prior operation. The op also didn't show up in /api/operations,
so the Backends UI couldn't reflect upgrade progress on the
affected row.

Register the op in opcache immediately, wrap it in a cancellable
context, store the cancellation function on the GalleryService,
and push onto the channel from a goroutine so the handler
returns right away. Response gains a `jobID` field and a
`message` string so clients have a consistent handle regardless
of whether the op is queued or running.

Pairs with the OnBackendOpCompleted hook added in the galleryop
commit — together the UI sees the upgrade start, watches
progress via /api/operations, and drops the "upgradeable" flag
the moment the worker finishes.

ecf85fde9e fix(api): remove duplicate /api/traces endpoint that broke React UI (#9427)
The API Traces tab in /app/traces always showed (0) traces despite requests
being recorded.

The /api/traces endpoint was registered in both localai.go and ui_api.go.
The ui_api.go version wrapped the response as {"traces": [...]} instead of
the flat []APIExchange array that both the React UI (Traces.jsx) and the
legacy Alpine.js UI (traces.html) expect. Because Echo matched the ui_api.go
handler, Array.isArray(apiData) always returned false, making the API Traces
tab permanently empty.

Remove the duplicate endpoints from ui_api.go so only the correct flat-array
version in localai.go is served.

Also use mime.ParseMediaType for the Content-Type check in the trace
middleware so requests with parameters (e.g. application/json; charset=utf-8)
are still traced.

75a63f87d8 feat(distributed): sync state with frontends, better backend management reporting (#9426)
* fix(distributed): detect backend upgrades across worker nodes

Before this change `DistributedBackendManager.CheckUpgrades` delegated to the
local manager, which read backends from the frontend filesystem. In
distributed deployments the frontend has no backends installed locally —
they live on workers — so the upgrade-detection loop never ran and the UI
silently never surfaced upgrades even when the gallery advertised newer
versions or digests.

Worker-side: NATS backend.list reply now carries Version, URI and Digest
for each installed backend (read from metadata.json).

Frontend-side: DistributedBackendManager.ListBackends aggregates per-node
refs (name, status, version, digest) instead of deduping, and CheckUpgrades
feeds that aggregation into gallery.CheckUpgradesAgainst — a new entrypoint
factored out of CheckBackendUpgrades so both paths share the same core
logic.

Cluster drift policy: when per-node version/digest tuples disagree, the
backend is flagged upgradeable regardless of whether any single node
matches the gallery, and UpgradeInfo.NodeDrift enumerates the outliers so
operators can see *why* it is out of sync. The next upgrade-all realigns
the cluster.

Tests cover: drift detection, unanimous-match (no upgrade), and the
empty-installed-version path that the old distributed code silently
missed.

* feat(ui): surface backend upgrades in the System page

The System page (Manage.jsx) only showed updates as a tiny inline arrow,
so operators routinely missed them. Port the Backend Gallery's upgrade UX
so System speaks the same visual language:

- Yellow banner at the top of the Backends tab when upgrades are pending,
  with an "Upgrade all" button (serial fan-out, matches the gallery) and a
  "Updates only" filter toggle.
- Warning pill (↑ N) next to the tab label so the count is glanceable even
  when the banner is scrolled out of view.
- Per-row labeled "Upgrade to vX.Y" button (replaces the icon-only button
  that silently flipped semantics between Reinstall and Upgrade), plus an
  "Update available" badge in the new Version column.
- New columns: Version (with upgrade + drift chips), Nodes (per-node
  attribution badges for distributed mode, degrading to a compact
  "on N nodes · M offline" chip above three nodes), Installed (relative
  time).
- System backends render a "Protected" chip instead of a bare "—" so rows
  still align and the reason is obvious.
- Delete uses the softer btn-danger-ghost so rows don't scream red; the
  ConfirmDialog still owns the "are you sure".

The upgrade checker also needed the same per-worker fix as the previous
commit: NewUpgradeChecker now takes a BackendManager getter so its
periodic runs call the distributed CheckUpgrades (which asks workers)
instead of the empty frontend filesystem. Without this the /api/backends/
upgrades endpoint stayed empty in distributed mode even with the protocol
change in place.

New CSS primitives — .upgrade-banner, .tab-pill, .badge-row, .cell-stack,
.cell-mono, .cell-muted, .row-actions, .btn-danger-ghost — all live in
App.css so other pages can adopt them without duplicating styles.

* feat(ui): polish the Nodes page so it reads like a product

The Nodes page was the biggest visual liability in distributed mode.
Rework the main dashboard surfaces in place without changing behavior:

StatCards: uniform height (96px min), left accent bar colored by the
metric's semantic (success/warning/error/primary), icon lives in a
36x36 soft-tinted chip top-right, value is left-aligned and large.
Grid auto-fills so the row doesn't collapse on narrow viewports. This
replaces the previous thin-bordered boxes with inconsistent heights.

Table rows: expandable rows now show a chevron cue on the left (rotates
on expand) so users know rows open. Status cell became a dedicated chip
with an LED-style halo dot instead of a bare bullet. Action buttons gained
labels — "Approve", "Resume", "Drain" — so the icons aren't doing all
the semantic work; the destructive remove action uses the softer
btn-danger-ghost variant so rows don't scream red, with the ConfirmDialog
still owning the real "are you sure". Applied cell-mono/cell-muted
utility classes so label chips and addresses share one spacing/font
grammar instead of re-declaring inline styles everywhere.

Expanded drawer: empty states for Loaded Models and Installed Backends
now render as a proper drawer-empty card (dashed border, icon, one-line
hint) instead of a plain muted string that read like broken formatting.

Tabs: three inline-styled buttons became the shared .tab class so they
inherit focus ring, hover state, and the rest of the design system —
matches the System page.

"Add more workers" toggle turned into a .nodes-add-worker dashed-border
button labelled "Register a new worker" (action voice) instead of a
chevron + muted link that operators kept mistaking for broken text.

New shared CSS primitives carry over to other pages:
.stat-grid + .stat-card, .row-chevron, .node-status, .drawer-empty,
.nodes-add-worker.

* feat(distributed): durable backend fan-out + state reconciliation

Two connected problems handled together:

1) Backend delete/install/upgrade used to silently skip non-healthy nodes,
   so a delete during an outage left a zombie on the offline node once it
   returned. The fan-out now records intent in a new pending_backend_ops
   table before attempting the NATS round-trip. Currently-healthy nodes
   get an immediate attempt; everyone else is queued. Unique index on
   (node_id, backend, op) means reissuing the same operation refreshes
   next_retry_at instead of stacking duplicates.

2) Loaded-model state could drift from reality: a worker OOM'd, got
   killed, or restarted a backend process would leave a node_models row
   claiming the model was still loaded, feeding ghost entries into the
   /api/nodes/models listing and the router's scheduling decisions.

The existing ReplicaReconciler gains two new passes that run under a
fresh KeyStateReconciler advisory lock (non-blocking, so one wedged
frontend doesn't freeze the cluster):

  - drainPendingBackendOps: retries queued ops whose next_retry_at has
    passed on currently-healthy nodes. Success deletes the row; failure
    bumps attempts and pushes next_retry_at out with exponential backoff
    (30s → 15m cap). ErrNoResponders also marks the node unhealthy.

  - probeLoadedModels: gRPC-HealthChecks addresses the DB thinks are
    loaded but hasn't seen touched in the last probeStaleAfter (2m).
    Unreachable addresses are removed from the registry. A pluggable
    ModelProber lets tests substitute a fake without standing up gRPC.

DistributedBackendManager exposes DeleteBackendDetailed so the HTTP
handler can surface per-node outcomes ("2 succeeded, 1 queued") to the
UI in a follow-up commit; the existing DeleteBackend still returns
error-only for callers that don't care about node breakdown.

Multi-frontend safety: the state pass uses advisorylock.TryWithLockCtx
on a new key so N frontends coordinate — the same pattern the health
monitor and replica reconciler already rely on. Single-node mode runs
both passes inline (adapter is nil, state drain is a no-op).

Tests cover the upsert semantics, backoff math, the probe removing an
unreachable model but keeping a reachable one, and filtering by
probeStaleAfter.

* feat(ui): show cluster distribution of models in the System page

When a frontend restarted in distributed mode, models that workers had
already loaded weren't visible until the operator clicked into each node
manually — the /api/models/capabilities endpoint only knew about
configs on the frontend's filesystem, not the registry-backed truth.

/api/models/capabilities now joins in ListAllLoadedModels() when the
registry is active, returning loaded_on[] with node id/name/state/status
for each model. Models that live in the registry but lack a local config
(the actual ghosts, not recovered from the frontend's file cache) still
surface with source="registry-only" so operators can see and persist
them; without that emission they'd be invisible to this frontend.

Manage → Models replaces the old Running/Idle pill with a distribution
cell that lists the first three nodes the model is loaded on as chips
colored by state (green loaded, blue loading, amber anything else). On
wider clusters the remaining count collapses into a +N chip with a
title-attribute breakdown. Disabled / single-node behavior unchanged.

Adopted models get an extra "Adopted" ghost-icon chip with hover copy
explaining what it means and how to make it permanent.

Distributed mode also enables a 10s auto-refresh and a "Last synced Xs
ago" indicator next to the Update button so ghost rows drop off within
one reconcile tick after their owning process dies. Non-distributed
mode is untouched — no polling, no cell-stack, same old Running/Idle.

* feat(ui): NodeDistributionChip — shared per-node attribution component

Large clusters were going to break the Manage → Backends Nodes column:
the old inline logic rendered every node as a badge and would shred the
layout at >10 workers, plus the Manage → Models distribution cell had
copy-pasted its own slightly-different version.

NodeDistributionChip handles any cluster size with two render modes:
  - small (≤3 nodes): inline chips of node names, colored by health.
  - large: a single "on N nodes · M offline · K drift" summary chip;
    clicking opens a Popover with a per-node table (name, status,
    version, digest for backends; name, status, state for models).

Drift counting mirrors the backend's summarizeNodeDrift so the UI
number matches UpgradeInfo.NodeDrift. Digests are truncated to the
docker-style 12-char form with the full value preserved in the title.

Popover is a new general-purpose primitive: fixed positioning anchored
to the trigger, flips above when there's no room below, closes on
outside-click or Escape, returns focus to the trigger. Uses .card as
its surface so theming is inherited. Also useful for a future
labels-editor popup and the user menu.

Manage.jsx drops its duplicated inline Nodes-column + loaded_on cell
and uses the shared chip with context="backends" / "models"
respectively. Delete code removes ~40 lines of ad-hoc logic.

* feat(ui): shared FilterBar across the System page tabs

The Backends gallery had a nice search + chip + toggle strip; the System
page had nothing, so the two surfaces felt like different apps. Lift the
pattern into a reusable FilterBar and wire both System tabs through it.

New component core/http/react-ui/src/components/FilterBar.jsx renders a
search input, a role="tablist" chip row (aria-selected for a11y), and
optional toggles / right slot. Chips support an optional `count` which
the System page uses to show "User 3", "Updates 1" etc.

System Models tab: search by id or backend; chips for
All/Running/Idle/Disabled/Pinned plus a conditional Distributed chip in
distributed mode. "Last synced" + Update button live in the right slot.

System Backends tab: search by name/alias/meta-backend-for; chips for
All/User/System/Meta plus conditional Updates / Offline-nodes chips
when relevant. The old ad-hoc "Updates only" toggle from the upgrade
banner folded into the Updates chip — one source of truth for that
filter. Offline chip only appears in distributed mode when at least
one backend has an unhealthy node, so the chip row stays quiet on
healthy clusters.

Filter state persists in URL query params (mq/mf/bq/bf) so deep links
and tab switches keep the operator's filter context instead of
resetting every time.

Also adds an "Adopted" distribution path: when a model in
/api/models/capabilities carries source="registry-only" (discovered on
a worker but not configured locally), the Models tab shows a ghost chip
labelled "Adopted" with hover copy explaining how to persist it — this
is what closes the loop on the ghost-model story end-to-end.

8ab0744458 feat: backend versioning, upgrade detection and auto-upgrade (#9315)
* feat: add backend versioning data model foundation

Add Version, URI, and Digest fields to BackendMetadata for tracking
installed backend versions and enabling upgrade detection. Add Version
field to GalleryBackend. Add UpgradeAvailable/AvailableVersion fields
to SystemBackend. Implement GetImageDigest() for lightweight OCI digest
lookups via remote.Head. Record version, URI, and digest at install time
in InstallBackend() and propagate version through meta backends.

* feat: add backend upgrade detection and execution logic

Add CheckBackendUpgrades() to compare installed backend versions/digests
against gallery entries, and UpgradeBackend() to perform atomic upgrades
with backup-based rollback on failure. Includes Agent A's data model
changes (Version/URI/Digest fields, GetImageDigest).

* feat: add AutoUpgradeBackends config and runtime settings

Add configuration and runtime settings for backend auto-upgrade:
- RuntimeSettings field for dynamic config via API/JSON
- ApplicationConfig field, option func, and roundtrip conversion
- CLI flag with LOCALAI_AUTO_UPGRADE_BACKENDS env var
- Config file watcher support for runtime_settings.json
- Tests for ToRuntimeSettings, ApplyRuntimeSettings, and roundtrip

* feat(ui): add backend version display and upgrade support

- Add upgrade check/trigger API endpoints to config and api module
- Backends page: version badge, upgrade indicator, upgrade button
- Manage page: version in metadata, context-aware upgrade/reinstall button
- Settings page: auto-upgrade backends toggle

* feat: add upgrade checker service, API endpoints, and CLI command

- UpgradeChecker background service: checks every 6h, auto-upgrades when enabled
- API endpoints: GET /backends/upgrades, POST /backends/upgrades/check, POST /backends/upgrade/:name
- CLI: `localai backends upgrade` command, version display in `backends list`
- BackendManager interface: add UpgradeBackend and CheckUpgrades methods
- Wire upgrade op through GalleryService backend handler
- Distributed mode: fan-out upgrade to worker nodes via NATS

* fix: use advisory lock for upgrade checker in distributed mode

In distributed mode with multiple frontend instances, use PostgreSQL
advisory lock (KeyBackendUpgradeCheck) so only one instance runs
periodic upgrade checks and auto-upgrades. Prevents duplicate
upgrade operations across replicas.

Standalone mode is unchanged (simple ticker loop).

* test: add e2e tests for backend upgrade API

- Test GET /api/backends/upgrades returns 200 (even with no upgrade checker)
- Test POST /api/backends/upgrade/:name accepts request and returns job ID
- Test full upgrade flow: trigger upgrade via API, wait for job completion,
  verify run.sh updated to v2 and metadata.json has version 2.0.0
- Test POST /api/backends/upgrades/check returns 200
- Fix nil check for applicationInstance in upgrade API routes

e0ab1a8b43 fix: use exact tag matching for model gallery tag filtering (#9041)
The Search() method uses strings.Contains() on comma-joined tags,
causing substring false positives (e.g., "asr" matching "image-diffusers").

Add FilterByTag() method that checks each tag with strings.EqualFold()
for exact, case-insensitive matching. Add 'tag' query parameter to
/api/models and /api/backends endpoints. Update the React frontend to
send filter selections as 'tag' instead of 'term'.

4cd95b8a9d fix: Highly inconsistent agent response to cogito agent calling MCP server - Body "Invalid http method" (#7790)
* fix: resolve duplicate MCP route registration causing 50% failure rate

Fixes #7772

The issue was caused by duplicate registration of the MCP endpoint
/mcp/v1/chat/completions in both openai.go and localai.go, leading
to a race condition where requests would randomly hit different
handlers with incompatible behaviors.

Changes:
- Removed duplicate MCP route registration from openai.go
- Kept the localai.MCPStreamEndpoint as the canonical handler
- Added all three MCP route patterns for backward compatibility:
  * /v1/mcp/chat/completions
  * /mcp/v1/chat/completions
  * /mcp/chat/completions
- Added comments to clarify route ownership and prevent future conflicts
- Fixed formatting in ui_api.go

The localai.MCPStreamEndpoint handler is more feature-complete as it
supports both streaming and non-streaming modes, while the removed
openai.MCPCompletionEndpoint only supported synchronous requests.

This eliminates the ~50% failure rate where the cogito library would
receive "Invalid http method" errors when internal HTTP requests were
routed to the wrong handler.
